TL;DR
This paper explores how quantum vacuum polarization causes birefringence, altering photon velocities in Schwarzschild spacetime, which could impact our understanding of light propagation near black holes.
Contribution
It introduces a quantum modification to null trajectories in Schwarzschild spacetime, revealing polarization-dependent photon velocity changes due to vacuum polarization effects.
Findings
Photon velocities depend on polarization in curved spacetime.
Vacuum polarization induces birefringence near black holes.
Photon trajectories are modified by quantum effects in Schwarzschild spacetime.
Abstract
The photon vacuum polarization effect in curved spacetime leads to birefringence, i.e. the photon velocity becomes greater than (or less than) the speed of light depending on its polarization. We investigate this phenomenon in a Schwarzschild curved spacetime.
